Larry, I only run Novak Gtb esc's and have never blown one. I also use a 3.5t in mod fttc4, and the speedo and motor are so cool at the end of the 6minute runs that I ordered a kinetic to add some timing(10°) from 45000rpm up to 50000rpm.With the gtb, I am not losing anything on the top end to the tekins and SP that I race against. I believe the kinetic will handle it well. On the bottom end though the gtb 3.5t kills everybody, and when you add the small timing(2° to 10°) at the top end with the kinetic, it will be over for tekin or Sp ! I think Novak is better suited for shaft cars with low friction bearings, and seem to smoke in belt cars ......
